Gretchen Rossi: Leaving the O.C. for the Music Biz?

Well, not exactly — but the unmarried Real Housewives of Orange County star did hint at what her next business venture may be.

“I’m planning to do something in the music business,” she told us Sunday night at the American Music Awards. “I’m here to support the industry and I love it.”

Though she “can’t say” what exactly she has up her sleeve, one thing’s for sure: she says she’s a huge fan of all music genres.

What would fans be surprised to know is on her iPod? “Songs that are in my music catalogue, which is a lot of songs! I could pull out a whole list,” she said. Boyfriend Slade Smiley quipped that she “owns publishing rights to Ashley Tisdale.”

If she does decide to sing, Gretchen won’t be the only chanteuse in the Housewives clique — Kim Zolciak showcased her…umm…talents when she performed “Tardy for the Party” at the Real Housewives of Atlanta reunion show earlier this month.

Tell us: In a musical Housewives duel, who do you think will have the more successful career? Gretchen or Kim?
